This doesn't work. You need energy to convert CO2 back into propane. The CO2 is coming from fossil fuels, which you're still ultimately going to burn again to get energy back...putting the CO2 back into the atmosphere.
Only now you've thrown away some of the energy in losses doing the CO2 to propane conversion.
This would lower the efficiency of a fossil fuel powerplant, and this increase the CO2 emitted overall.
- malfist 3y agoOnly if you use energy from fossil fuels to do the conversion. Earth's energy isn't a zero sum game, we have plenty of decarbonized energy sources.
- rocqua 3y agoI meant to do the CO2 capture at gas furnaces in homes. Because the electric power available for heating is ofte limited, but might still be sufficient to gather CO2 from the exhaust of the furnace. It'll cost energy, but it is a cheap source of CO2 for this electrolysis.
- XorNot 3y agoTo convert CO2 back to propane you have to put in every bit of energy released when burning it and then some. So again, it wouldn't work because as you note: the electric power available is less than the gas.
